okay for the sake of ls1 being faster than lt1, the ls1 has bigger heads and valves and a larger cam, being a large factor to its horsepower gain, if you spec them the same youll have comparable horsepower. and the fact that it is an aluminum block helps a lil, but i like my lt1 far better than any ls1 ive driven

 

Hey there CDN..

An LS1 car will be capable of low 13s with no mods. Most LT1s are low 14s with no mods.

The LT1 FEELS like it has more guts in around town driving due to the lower RPM torque. You just hafta drive an LS1 like a european engine ... use the RPM.

Put the same money into both & the LS1 will gain more power than the LT1. The head design is just so much better.

You can have a 12 second LS1 pretty easily. simple bolt-ons will get you there. Such as:

Lid & filter
Chip
free mods like the EGR tube & porting the MAF
Exhaust (don't even need a header to do 12s, if the other stuf is done)
Gears and/or Torque Converter

ls1>lt1 stock
ls1=lt1 modded

ofcourse the ls1 is faster stock, if any1 argues that point they are lost...but who really cares about stock? is it going to stay stock? probably not if you are on here

i contest the idea that the ls1 will just be faster and is just plain better no matter what, cuz thats not right...

and if you say "put the same $ into an ls1 and lt1" then include the cost of the car in that...and that makes the lt1 as cheap or cheaper to run the same time

i have nothing against the LS1, only against those that think its the god of automotive engineering...its a SBC, new, well designed, but modded for modded it can be beat and has been beat...it isnt forged from the hands of god to be faster

 

Of course in respect to overall cost & bang for the buck...

You can't beat an LT1 4th gen.

Shoot, for $10,000 (and even less), you can build a super 11 second street & track fighter. You can't even buy a stock LS1 car for that, yet. If cost is a factor (and of course it ususlly is...) LT1 cars are the king of hot street & track performance & ability to mod.

All versions of the SBCs have always been known for great modability due to the great engineering in the first place.

I like working the LS1, because it's the new kid on the block. Not as "tried & true" .... although it's getting there. I've done a bunch of SBCs & BBCs (although no LT1s) over the years... I'm ready for an all new challenge.

There shouldn't be a fight over what's best..... just choose your preferences & go have fun (cost, potential modability, availability, parst cost & availability, etc..)!

Now be nice & make up....

M3, how about the ability to hold sustained RPMs w/o damage?.I mean what is a safe range to hold a gear for periods at higher rpms like in road race atmosphere where you hold gear and rev it up in the turns in stead of takin the shift mid turn.?Or shorter lengnths were you know you'll be slowing again anyway decide to keep the gear yer in manhandle it at the high range for periods.

 

thats because they are....

do u know what lt1s run in the quarter??? low 14s
a stock ls1 with a good driver can break into the 12s.....well it will hit low 13s all day long anyway......

of course this is all stock.....

 

The LS1 is a newer, better design from the start and is a better breathing/HP making motor than the LT1 in all respects until you go FI, or HUGE horsepower. In those cases, the LT1s stronger block and crank/head bolt strength will come into play. Bolt-ons? LS1. Heads/cam? LS1. Nitrous? Up to a certain point, LS1. The lighter block and bigger brakes favor the LS1 as well. If you are building a street car that will go to the track once in a while, LS1 all the way. If you are building a dedicated track car, I would go with the LT1 as it is cheaper for comparitive HP levels.

 

i just said:
who cares what it runs stock, its not gonna stay stock...unless people with ls1's wanna run me thinking im stock or that they cant lose cuz its impossible for the ls1 to lose, thats fine by me....

 

or this topic is about a guy that wants to get lt1 or ls1....so we are telling him which way to go

and believe it or not many ppl keep their cars stock

 

he wants to know whether or not to switch and some of the advice he gets sounds like 'ls1 is so much better in every way..stock, modded, its not even close, why ask, ofcourse do the ls1' i mean come on

i just gotta stick up for the lt1, it doesnt take much to make them quick either, and ull get the car much cheaper

and if you are on an fbody forum and asking about performance issues, i think we can assume mods are possible in the future

either way, if he has the $ and doesnt want to mod much, buy an ls1 car, its faster stock and newer

if he doesnt have the $ go lt1

and if its not all about the $ but it will be modded, then go with either, there is no clear cut winner

 

well since his 97 is stock we can assume that that statement is blatantly false...

I can mod a civic to beat most of the LS1 cars on here. does that mean then, that civics are equal to the LS1 when it comes to performance?



modded vs modded, is not a true comparison of the vehicles unless the mods are spelled out. so for comparison sake stock vs stock is the generaly accepted standard, simply because there are way too many variations on modded. Unfortunately we simply dont have the server space to list every possible senario of modded cars racing.

and of course if the LS1 has a guy who cant drive his way out of a paper bag behind the wheel, he will lose to an LT1 with a pro. so for comparison the drivers are generaly considered equal.

And the fact still remains that given those circumstances the LS1 wins.

 

This is not true either, it depends on what direction and how far he wants to go with the mods. In some cases there will be a very obvious winner, others there wont, but again, space kinda limits our ability to list all possibilities

 

TeeeHeeeHeee...

I just hafta laugh at this discusion every time I see it come up...


Such passion!

 

Ok for anyone who can't understand this is how it works.

LS1 > LT1 STOCK!
LS1 > LT1 Bolt ons
LS1 > LT1 Heads & Cam and all the boltons.
LS1 < LT1 When used for forced induction.

I believe that the LS1 is superior in every way except for forced induction. If you were going to build a motor from scratch and you are planning on using a blower or a turbo(s) I would pick a LT1 over a LS1. Why? I believe that a properly built LT1 will take more boost than well built LS1. But what do I know? Anyone else agree with me?

 

How do you figure the LS1 is less friendly when using forced induction?
